Third Edition 30,000, September 25th, 1917. PRESS OF ISAAC GOLDMANN COMPANY, NEW YORK NOTICE There is a wealth of material in this little book that will interest the soldier. From the illustrations alone he will be able to obtain a good general idea of the subject. It is essentially a soldier's book, written in language that he can understand. The price has been kept within the limits of his pocketbook. With a view to securing a wide distribution of the book I desire to secure a representative in every organization in the Army. I have an attractive proposition to make to competent parties. A letter will bring particulars. My address will be found in the Army List and Directory. If this is not available, a letter addressed as follows will be forwarded to me: Captain W.H. Waldron, 29th Infantry, Care of "Infantry Journal," Washington, D.C. (Signed) W.H. Waldron.
